SEOUL, SOUTH KOREA — Satellite imagery suggests North Korea is making “wide-ranging, extensive” efforts to fully reactivate its main nuclear complex, a US think tank said Tuesday, in line with Pyongyang’s vows to strengthen its weapons program.

Recent images show work at the Yongbyon nuclear compound apparently aimed at producing fuel rods to be used in a plutonium reactor, Johns Hopkins University’s US-Korea Institute said.

Analysis of the imagery identified one “probable fuel fabrication plant” for the 5-megawatt plutonium reactor that reopened earlier this year, researcher Nick Hansen wrote on the institute’s blog, 38 North.

The isolated communist state staged its third nuclear test in February — its most powerful to date — after two previous tests in 2006 and 2009.

Two months later, it boasted that it would reopen the Yongbyon nuclear compound in the northwest that had been shut since 2007, in order to bolster its atomic arsenal.

“The soot on the new roof shows that a heating process had occurred, such as the use of metal casting furnaces necessary to complete the heat treatment during the fuel rod assembly,” Hansen wrote.

A white stain on the roof of the facility was believed to be hydrofluoric acid used to produce fuel rods.

A nearby venue that appears to be a dumping site showed a large amount of “gray materials” suspected to be ash from the fuel rod production process, he added.

“The identification of these facilities indicates a more wide-ranging, extensive effort by North Korea to modernize and restart the Yongbyon complex ... than previously understood,” he wrote.

Pyongyang’s current stockpile of nuclear materials — mostly plutonium — is variously estimated as being enough for six to 10 bombs.

The shock execution of North Korean leader Kim Jong-Un’s powerful uncle two weeks ago raised concerns over potential instability in the North or military provocations such as an atomic test aimed at rallying domestic unity.

South Korean defense and intelligence chiefs however ruled out the possibility of imminent atomic test despite continued preparations.

Nam Jae-Joon, chief of the South’s intelligence agency, told lawmakers on Monday that the North was capable of staging another atomic test anytime but had so far showed no signs of doing so.
